Equal number of births and deaths

Vedclass · Answer

(D) The zero growth phase,also known as a stable population,occurs when the birth rate is exactly equal to the death rate. In this state,the population size remains constant over time because the number of individuals added to the population through births is balanced by the number of individuals lost through deaths. Mathematically,this is represented as $r = 0$ (where $r$ is the intrinsic rate of natural increase).

Column-$I$ (Value of $r$)	Column-$II$ (Example)
$P. 0.12$	$I$. Flour beetle
$Q. 0.015$	$II$. Norway rat
$R. 0.0205$	$III$. Human population in India in $1981$
